Abstract: A structural system is comprised of two components. The first component is an I-shaped bearing member having an upper flange and a lower flange connected by a web. The upper and lower flanges have undercuts formed therein. The second component is a connection member having a notch in each corner for engaging the undercuts in the upper and lower flanges. The components of this system may be used to construct a structural component comprising a plurality of I-shaped bearing members positioned parallel to one another. A plurality of connection members interconnect the bearing members; the two upper notches of the connection member engage the undercuts in the upper flanges of two adjacent bearing members while the two lower notches engage the undercuts in the lower flanges of two adjacent bearing members. A method of constructing a structural component is comprised of positioning a plurality of bearing members parallel to one another.

Abstract: A method for producing a pultrusion product having a variable cross-section using a specially adapted temperature controllable pultrusion die includes the steps of pulling reinforcing fibers which have been impregnated with a heat curable thermosetting polymeric resin composition through a temperature controllable die, heating the temperature controllable die to a temperature sufficient to effect curing of the thermosetting resin, cooling the temperature controllable die to a temperature which is sufficiently low to prevent any significant curing of thermosetting resin passing through the pultrusion die, pulling the cured material and a predetermined length of uncured material from the die, reshaping the uncured material, and curing the reshaped material. The reshaping step can be used to provide off-sets, flanges, bosses and the like.

Abstract: A spacer strip for use in a sealed window unit is manufactured from a pultruded fibreglass reinforced body providing a substantially closed hollow body with a slot along one side. The strip is manufactured by pultrusion using a die which is slightly more open than the finished product including a mandrel supported by a web wider than the eventual slot. Closing of the body into the eventual shape is obtained either by differential shrinkage using matting on the outer surface of the body or by squeezing the body between heated rollers. A sealed window unit incorporates the spacer strips between two panes of glass adjacent the edges thereof and incorporates a dessicant communicating with the space between the windows through the slot.

Abstract: Disclosed is an apparatus and method for the distribution of composite mixtures into an initially open mold, such as the components utilized in the manufacture of frictional components containing asbestos. The apparatus includes a hopper or reservoir for holding and dispensing the mixture onto a collection surface and, suitable means for moving the collection surface relative to the hopper. A deflector is mounted below the hopper, while supply and feed rotors, separated by a reciprocator means are carried within the hopper. Means are further provided for driving the deflector, rotors and reciprocator. The apparatus may further include means for sweeping and levelling the composite mixture in the mold.
